sure, but this isn't that, as far as I can tell. both sides are acting in too...organized a way. what merchant would walk into a town where walking into the town (while being what the merchant is) is going to get you shot? More to the point, whatever this is, it's been going on long enough that gunning someone down in the street is "alright," and doing so in a way that leaves a gate unguarded - both speak of longer term conflicts, and the latter implies complacency from disuse. The raiders are, similarly, organized, and have a base, procedures, and a command structure; it feels polished "enough" to have been around for a while. Unless our friendly RV merchant hasn't been around for 6 months, this shouldn't be a surprise to him, and he should have warned her.
